Now that I use a a copoly, low tension, and restring before it goes dead, I haven't had any trouble at all with arm soreness from poly.
I agree with everything here. Well said and great advice. If only every stringer out there knew about this phenomenon, we'd have a lot less wrist and elbow overuse injuries out there.
